imp: heres' how...Answer to your first question...1)The marijuana plant is very hardy meaning, it can withstand temps as low as 40 deg. before it has major effects on growth (slowing) it depends alot on variety of plant. (which you failed to mention) Or the plant can withstand temps. as high as 120 deg. (don't recommend) The ideal temps. uaually fall in the range of 60-85 degrees the more light available, the ideal temp. for normal output increases. Night temps should be about 10-15 deg. lower than in day. In plain english,80 deg. daytime 65 deg. nighttime.2) MOLASSES?????
